Take a soft ruler, measure the dimension x 1. 1 horizontally around the product, and divide it by 2 to get the width of the bag. The dimension measured again around the longitudinal direction of the product is the same as x 1. 1, and the height of the bag is obtained by dividing by 2. When measuring vertically and horizontally, take the most prominent part of the product and don't dent the ruler.

The calculation method of PE bag weight is length * width * single thickness *2*0.93, and its thickness can be calculated by knowing its size and weight according to this formula.

When plastic bags are actually used, they should be slightly larger than the above dimensions, such as increasing by 5%, otherwise they will be too crowded. The above cuboid length, cuboid width and cuboid height meet the following requirements: cuboid length >; = width of cuboid >; = the height of the cuboid.
